HEAD OF SIPI-IONS FOR AERA'IED LIQUIDS.

Specification of Letters Patent.

Application filed April 9, 1912.

Patented J anfl, 1913. Serial No. 689,582.

To all whom it may concern Be it known that I, WILLIAM TREVENA lViLLIAMs Innis, a subject of the King of Great Britain, residing at 244 Camden road, Camden Town, in the county of London, England, have invented new and useful Improvements in the Heads of Siphons for Aerated Liquids, of which the following IS a specification.

Siphon heads as at present constructed often consist of a metal tube or cylinder which screws onto a split ring around the neck of the vase, a china block having an axial hole through it and a nozzle at one side projecting through the cylinder, a cap screwing onto the top of the cylinder and a flexible disk valve pressed down. by a spring against the middle of the block and lifted by a lever. In such heads the joints between the block and the vase and between the circumference of the disk valve and the block are usually both made by screwing down the cap and thus compressing an annular washer and the disk respectively. Such arrangements have the following disadvantages: 1. It is dificult to get proper joints and at the same time to get the nozzle and the lever exactly opposite one another without exposing part of the screw thread at the top. 2. It is impossible to test the valve until the head is in place and this involves a waste of time and unnecessary wear of the parts by screwing and unscrewing them. 3. If the cap bears on the ring by which the circumference of the disk is pressed onto the block then the screwing on of the cap is apt to displace and rub the disk.

The object of this invention is to avoid these disadvantages. This is done by securing the block within the cylinder before the head is put onto the vase by means of a collar screwing inside the cylinder and forcing the block upward thus compressing the valve spring and pressing the circumference of the disk firmly against the block. After the parts have been secured in place in this manner the valve can be tested. The complete head with the parts secured in it is then screwed onto the split ring around the neck of the vase, an annular washer being interposed as usual between the top of the neck and the block.

In the accompanying drawings: Figure 1 is a view partly in vertical section and partly in elevation of the top of a siphon constructed in accordance with this invention. Fig. 2 shows a vertical central section through the siphon head detached from the vase or bottle.

The tube or cylinder 0 of the head is attached to the vase A by means of a. split ring 5 in the usual way. The block (Z of the kind well known in this art is formedwith a central aperture (Z and a spout d This block fits in the tube or cylinder 0 closely in the manner shown. The cap 6 has a threaded connection with the upper end of the cylinder 0 and within this cap is a spring 70 hearing on a plunger Z connected at f with the flexible disk valve f. The plunger Z is operated by the lever g. m indicates a ring of the kind heretofore employed resting on top of the disk valve f and on the upper edge of which the lever g bears when the latter is depressed. it indicates a washer interposed between the block 03 and the top of the neck of the vase. The construction and operation of these parts are well known and require no further description.

j indicates a collar forming the subject of the present invention. As shown it screws into the cylinder 0 and bears against the underside of the block (Z so that the latter can be forced up to any desired extent against the force of the spring 70. The collar may be formed with lugs. j or other devices which may be engaged by a suitable tool for turning it. The cap may be screwed on to the cylinder 0 so as to completely cover the threads at the upper ends thereof and so as to hold the lever g exactly opposite the spout OZ and then the block d may, if desired, be forced upwardly in the cylinder so as to press it firmly against the disk valve f which is pressed downward by the spring 7a. In this condition the valve and joints may be tested before the head is applied to the siphon and after this the head may be applied to the neck of the vase in the manner indicated in Fig. 1, the washer it being applied between the bottom of the block d and the upper edge of the neck. By means of the split ring I) the head'inay be drawn tightly down upon the neck of the vase and securely fastened thereto.

I claim as my invention:

The combination of the block provided with a nozzle and having a vertical opening through it, a cylinder surrounding the block and through which the nozzle extends, a

contained within the cap, connections 'below the block and pressing the block and valve covering the vertical opening in the spring, and a threaded split ring engaging block, a cap secured to the cylinder, a spring said cylinder.

between the spring and the valve, a threaded collar engaging the interior of the cylinder WILLIAM TREVENA WILLIAMS IDRIS.
